See the EXAMPLES section of "man lvextend".

yeh u r right
first you would increase size of LV and then would span the filesystem over that increased LV.

lvextend -L xxxxM /path/to/LV (be sure u have space in volume group)
fsadm -b xxxxM /mount_point

always have a look over man page before playing with filesystem ;)

Hi Unixuser,

Do you have jfs online feauture then you need to follow the Kapil's steps,

If you dont have online jfs feature then,

Ex:-

umount mount_directory
lvextend -L larger_size /dev/vg00/lvol1
extendfs -F fstype /dev/vg00/rlvol1
mount /dev/vg00/lvol1 mount_directory

and please assigne the points to my friends, I am not talking about me :)

Regards,
Rahul Rai.

# lvextend -L 522 /dev/vg00/lvol4 /dev/dsk/c3t5d
